Hardness is the basis of wear resistance. It is generally observed that the hardest materials have a higher resistance than less hard ones. Different work situations can be solved by using hard metal with WC-Co composition in the appropriate combination of composition and micro-structure.
Generally with the content of cobalt growing, there is also an increase in the wear factor, from the table it can be seen that the minimum wear value is reached with a content of 6% cobalt.
The use of hard metal in this area is very wide, a tin, a button, a chain, a magnetic stripe, a cigarette, a staple, a brick. All these at some stage of processing involve the use of modified hard metal in its composition and form.
